What it does
Cco Task is an agent skill from egorfedorov/claude-context-optimizer. Organize work by task, track tokens/cost per task, and keep a small patchable execution state that is re-injected after /compact (SKILL.state-style) — start a task, patch its state, list tasks, or mark the active one done. Pairs with /cco-pack to load minimal context per task.
Its SKILL.md is about 870 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: Claude Code plugin that tracks token usage, identifies wasted context, and saves 30-50% on API costs. Heatmaps, ROI reports, budget alerts, efficiency scores, git-aware… The licence is MIT.
Example prompts
- “/cco-task”
Requirements
- Pre-approved tools (allowed-tools): Bash(node ${CLAUDE_PLUGIN_ROOT}/src/tasks.js:*)
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- /cco-task add "implement X" — start the task
- /cco-pack "implement X" — load only the files that task needs
- /cco-task patch '{"goal": "...", "next": "..."}' — seed the state; patch as you go
- /cco — see budget, savings, and this task's cost
- /cco-task done — freeze the task's token/$ total
What it can do on your machine
Read from SKILL.md and the folder at commit f6f20ee. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
Bash(node ${CLAUDE_PLUGIN_ROOT}/src/tasks.js:*)
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
node
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Cco Task loads about 866 tokens when it runs. Until then it costs about 72 tokens; SKILL.md has 409 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Tasks — per-task context, cost, and execution state
A task is a named unit of work. While a task is active, the tokens the session
spends are attributed to it, so the Control Center (/cco) can show cost per
task, not just per session.
Each task also carries a small JSON execution state — goal, what is done,
what is open, the next action. You update it with patches instead of
re-deriving progress from the transcript, it is capped at ~1K tokens so it never
grows with the number of steps, and it is re-injected verbatim right after
/compact (and on --resume). That is the SKILL.state idea (Google / Purdue,
2026) applied where a plugin can apply it: the compaction summary is lossy and
free-form; the state is exact and bounded.
Commands
Parse the user's argument and run the matching command (working directory scopes the tasks to the current project):
Start / switch task (also closes the previous active task):
node ${CLAUDE_PLUGIN_ROOT}/src/tasks.js add "<task name>"After starting, suggest packing the minimal context for it:
/cco-pack "<task name>", and seed the state with the goal and the plan:
/cco-task patch '{"goal": "...", "plan": ["...", "..."], "next": "..."}'.
Patch the execution state (set keys; null deletes a key):
node ${CLAUDE_PLUGIN_ROOT}/src/tasks.js patch '{"done": ["read auth.ts"], "next": "write the failing test", "scratch": null}'The patch must be a JSON object. If the state would exceed the cap the patch is
rejected — prune finished keys with null first.
Show the current state:
node ${CLAUDE_PLUGIN_ROOT}/src/tasks.js stateList tasks (newest first, with per-task tokens + $):
node ${CLAUDE_PLUGIN_ROOT}/src/tasks.js listComplete the active task:
node ${CLAUDE_PLUGIN_ROOT}/src/tasks.js doneShow full SKILL.md (177 more words)Show less
State discipline (what makes it worth keeping)
- Keep it a state, not a log:
done,open,next,decisions,files— facts needed to continue, not the history of how you got there. Reasoning is ephemeral; the state is what survives. - Patch after each milestone (a test passing, a decision made, a file finished), and delete keys the moment they stop mattering.
- After
/compactthe SessionStart hook prints the active task's state into the new context automatically — treat it as authoritative over the summary. - When delegating to a subagent, pass the state (not the conversation) as the brief; it is already the minimal, current description of the task.
Flow to recommend
/cco-task add "implement X"— start the task/cco-pack "implement X"— load only the files that task needs/cco-task patch '{"goal": "...", "next": "..."}'— seed the state; patch as you go/cco— see budget, savings, and this task's cost/cco-task done— freeze the task's token/$ total
Only one task is active per project at a time; starting a new one finalizes the previous task's cost automatically.

Cco Task is an agent skill from egorfedorov/claude-context-optimizer.state-style) — start a task, patch its state, list tasks, or mark the active one done.
How do I install Cco Task in Claude Code?
Run `npx skills add egorfedorov/claude-context-optimizer --skill cco-task -a claude-code`. Or copy the skill folder (skills/cco-task in egorfedorov/claude-context-optimizer) into .claude/skills/cco-task in your project. Claude Code loads it when a task matches its description.
How do I install Cco Task in Codex?
Run `npx skills add egorfedorov/claude-context-optimizer --skill cco-task -a codex`. Or copy the skill folder (skills/cco-task in egorfedorov/claude-context-optimizer) into .agents/skills/cco-task in your project. Codex loads it when a task matches its description.
Can I use Cco Task in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add egorfedorov/claude-context-optimizer --skill cco-task -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/cco-task, .gemini/skills/cco-task, .github/skills/cco-task and .opencode/skills/cco-task in your project.
What does Cco Task need to run?
Going by SKILL.md and its folder, Cco Task needs the command-line tools its instructions call (node). Its frontmatter pre-approves these tools: Bash(node ${CLAUDE_PLUGIN_ROOT}/src/tasks.js:*).
Does Cco Task access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Cco Task safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
